SPIKE-FULLER.

' spike pullers.

One object of the invention is to provide a device of this character bymeans of which railroad and other forms of spikes may be readily drawn.

Another object is to provide a spike pulling device having means wherebythe fulcrum point of the spike pulling lever may be adjusted todifferent heights, to facilitate the drawing of long spikes.

A further object is to provide a spike puller having an adjustable railengaging foot on the lower end of the fulcrum stand ard whereby thedevice may be properly set on either side of the rail.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claim.

In the accompanying drawings: Figure 1 is a side View of my improvedspike puller showing the same in operative position and in the act ofdrawing a spike; Fig. 2 is a front view of the device with the parts inthe position shown in Fig. 1.; Fig. 3 is a side view of the deviceshowing the fulcrum standard in section to illustrate the constructionof the fulcrum bolt for the spike pulling lever and its engagement withthe bearing apertures in the standard and the construction of theadjustable foot of the standard; Fig. 41 is a front view of the fulcrumstandard showing the rail engaging foot of the same in a reverseposition to that shown in Fig. 2; Fig. 5 is a detail perspective view ofthe spike pulling lever showing the construction of the fulcrum bolttherein; Fig. 6 is a detail perspective view of one member of the spikepulling tongs.

Referring more particularly to the drawings 1 denotes the fulcrumstandard of my Specification of Letters Patent.

Serial No. 559,462.

improved spike pulling device, said standard having a bifurcated upperend which is of greater width than the main portion of the standard asshown thereby forming parallel fulcrum plates 2 in which are formedalined slots 3. The upper and lower ends of the slots 3 are enlarged toform circular hearing openings +1 and midway between the ends of theslots are formed pairs of oppositely disposed segmental notches whichform enlarged bearing openings 5. The enlarged portions of the slots orhearing openings 1 and 5 are provided to form adjustable bearings forthe fulcrum bolt of the spike pulling lever hereinafter described.

In the lower end of the standard is formed a centrally disposed verticalsocket 6 with which is engaged the shank 7 of a revolubly mounted footpiece 8 arranged on the lower end of the standard as shown. The shank 7of the foot piece is secured in the socket 6 by a set screw 9. In thelower end of the foot piece is formed a right angular rail engagingnotch 10 which is adapted to be engaged with the outer edges of the railflange. By revolubly mounting the foot piece 8 in the lower end of thestandard said foot piece may be turned upon loosening the set screw tobring the notch 10 opposite either edge of the standard thusfacilitating the engagement thereof with the flange on either side ofthe rail.

Arranged between the bifurcated upper end of the standard is a spikepulling lever 11 having on one end a handle socket 12 adapted to receivethe handle 13 which may be of any suitable length. Revolubly mounted inthe standard engaging portion of the lever is a fulcrum bolt 14 saidbolt being flattened or cut away on each side of the lever to form flatslot engaging portions 1!) which, when in vertical position or in linewith the slots, will permit the lever to be raised and lowered in thelatter to the desired elevation. Vhen opposite the bearing openings 4the bolt is turned in the lever to bring the widest part of the boltinto said openings wherein it is supported to fulcrum the lever 11. Thebolt is provided on one end with an operating head 16 and on itsopposite end with a clamping nut 17 whereby the bolt may be securedafter being adjusted to the desired bearing opening. By forming thefulcrum bolt in the manner described it will be readily seen that thesame may be adjusted to any of the bearing openings in the slots 3thereby fulcruming the lever at the desired elevation.

Pivotally connected to the outer end of the lever 11 is a pair of links18 in the lower ends of which is arranged the operating bolt 19 whichcarries tongs 20. The tongs consist of two spike gripping jaws ormembers 21 the upper portions of which are cut away or recessed to formoverlapping bearing lugs which are pivotally connected together by apivot bolt 22. On the upper ends of the jaws are formed inwardlyprojecting handle portions 23 which overlap and cross each other and areprovided with slots 24: through which is inserted the operating bolt 19in the lower ends of the links 18 whereby when said bolt is drawnupwardly by the links the lower spike engaging jaws of the tongs areforced into operative engagement with the head of a spike thereby firmlygripping the same so that when further pressure is applied to the leverthe spike will be extracted.

From the foregoing description taken in connection with the accompanyingdrawings the construction and operation of the invention will be readilyunderstood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruct-ion may be resorted to Without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claini.

Having thus described my invention what I claim is:

In a spike puller, a fulcrum standard bifurcated at its upper end toform parallel bearing plates having formed therein alined slots andbearing openings in the walls of the slots, a fulcrum bolt havingflattened slot engaging portions intermediate its ends whereby the boltmay be adjusted in said slots and turned into operative engagement withthe bearing openings formed therein, a turning knob on one end of saidbolt, a securing nut on the opposite end of the bolt, a spike pullinglever pivotally mounted on said fulcrum bolt, and a pair of spikepulling tongs connected with the lever.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FRANCIS M. WILLIAMS.
